One question to think about is how much longer you'd need to work in your current role to never have to worry about money again. Say you were to cut your expenses to the bare minimum, invest aggressively, and stick it out there another couple years. Would you have enough to be financially independent (FIRE)? I'm not usually one to advocate sticking it out at a job you don't like, but it seems you have a real chance to never have to worry about money again if you're willing to live a non-lavish lifestyle. Just something to consider.
